Build Your Skills: A comparison between DVD and CD-ROM That’s why CD-ROMs top out at about 650-700 MB of data, while DVDs can hold multiple gigabytes of data. Since the pits are more tightly written on a DVD disc, the mechanism in the drive for reading them also has to be finer and more precise. That’s the main reason that DVD drives cost more than CD-ROM drives. DVD drives can also read regular CD-ROM discs with no problem, since the difference is mostly in the spacing.

Why perform a meta-analysis? The meta-analysis serves to put the available data in context and to show the potential utility of the planned study. The graphical elements of the meta-analysis, such as the forest plot, provide a mechanism for presenting the data clearly, and for capturing the attention of the reviewers. Some funding agencies now require a meta-analysis of existing research as part of the grant application to fund new research.
